Description of key information

The Henry's Law Constant (HLC) of Fluorosulfonic Adduct is calculated to be 1653680 Pa m3/mol (20°C).

The values indicates that Fluorosulfonic Adduct has high tendency to distribute from water to the gas phase.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
1 653 680.41
at the temperature of:
20 °C

Additional information

The Henry's Law Constant (HLC) of Fluorosulfonic Adduct is calculated according to the following equation:

Henry's Law Constant (HLC) = (VP x MOLW) / WS

(Reference: Guidance on Information Requirements and Chemical Safety Assessment_ Chapter R.16:

Environmental Exposure Estimation_ Version 3_Equation R.16-4)

where:

VP = Vapour pressure (Pa) = 1828 Pa (at 20°C)

MOLW = Molecular Weight (g/mol) = 351 g/mol

WS = Water solubility (mg/L) = 0.388 mg/L (at 20°C)

 

As reported in Guidance on Information Requirements and Chemical Safety Assessment_Chapter R.7a_v.6., substances with HLC values around 100 Pa·m3/mol, will have a rapid volatilisationfrom water. Basing on the calculated Henry’s Law constant value, volatilization of Fluorosulfonic Adduct from water is expected to be rapid.
